Roto-Star 3

Roto-Star 3 is the latest generation precision rotary benchtop welding positioner designed to tackle a wide range of welding projects from pipe fittings to tubes and chassis.

The Roto-Star 3-P has the same features and benefits of the Roto Star 3 except that it comes equipped with a 406mm (16" inch) surface plate.


  • Can weld parts in horizontal or vertical positions or in 15° increments from 0 - 90°.
  • Dual grounding system makes it ideal for both aluminium and stainless steel applications.
  • 203mm diameter three-jaw self-centering chuck accepts parts of virtually any length through its unique 63.5mm spindle opening.
  • State of the art motor controller allows variable spindle RPM and forward or reverse rotation.
  • Heavy duty motor runs on direct current and delivers smooth and accurate spindle rotation.
  • Can make positive starts and stops without coasting or backlash.
  • Standard start/stop foot pedal frees hands to concentrate on welding.
  • Jitter free movement.
  • 360° rotation enables continuous weld, minimising operator movement and repositioning of material.
